I tried to document the clocks provided by RTEMS, see tail of
(glossary.rst):
https://lists.rtems.org/pipermail/devel/2021-February/064451.html
<https://lists.rtems.org/pipermail/devel/2021-February/064451.html>
Is it sufficient to reference the epoch entry in various clock get
time method pages?
The relevant epoch and clock is now referenced in the directives.
And should there be discussion somewhere about TZ environment variable
and the methods in newlib which account for that.
I think a time zone is simply not accounted for in the RTEMS Classic
API. With the setting above I guess the time zone is fixed to UTC.
